What defines a store that combines a supermarket and a department store under one roof?

A store that combines a supermarket and a department store under one roof is referred to as a supercenter. This retail format merges the features of a full-service grocery store with a wide range of general merchandise, including clothing, electronics, and household goods, all in a single location.

This concept allows consumers to fulfill multiple shopping needs in one stop, enhancing convenience and providing a broader selection of products. Supercenters typically operate on a larger scale compared to traditional supermarkets, offering competitive pricing and diverse product assortments.

The format is particularly popular in many regions as it appeals to shoppers looking for both grocery items and other retail goods, supporting a one-stop shopping experience that saves time and effort. Other retail types mentioned do not encompass this particular combination of supermarket and department store features, which is what clearly defines a supercenter.
